Abstract

Cancer-related fatigue (CRF) is a multidimensional syndrome which occurs in the majority of cancer patients during anticancer treatment and potentially persists for many years after cure. Because of its multidimensionality, CRF is influenced by physical, psychological and also social factors. Summarized by an article of the Cochrane Collaboration, exercise is a promising intervention for the treatment of CRF in breast cancer patients. However, little is known about the effects of exercise and its biological mechanisms in cancer patients during radio-therapy.   Further, nearly all studies in this field examined the effect of exercise against treatment-as-usual, mostly in group settings. Therefore, it is currently unknown if the beneficial effects are related to the physical training itself or caused by group-related psychosocial effects. Thus, the BEST study was designed to evaluate the potential benefits of progressive resistance training beyond group-related psychosocial effects and to evaluate potential biologic mechanisms.

BEST was a randomized controlled clinical trial, aimed to evaluate the effect of a high intensity, supervised and group-based resistance training on CRF in breast cancer patients during adjuvant radiotherapy, compared with a Progressive Muscle Relaxation (PMR) program.

All participants were requested to fill out standardized questionnaires concerning fatigue, quality of life and depression. In addition, physical performance (endurance and strength capacity), activity history and cognitive capacity will be assessed. Furthermore, blood, urine and saliva samples were collected for multiple analyses of immunological and inflammatory parameters and other biomarkers. The interventions started in parallel with the radiotherapy and ended after 24 sessions (2x/week) at week 13. Randomization was performed stratified for age and baseline fatigue levels. Data collection was performed at baseline (which is before start of radiotherapy), at end of radiotherapy, end of 12-week intervention, 3 months after end of radiotherapy, and 6 and 12 months after end of intervention.

Recruitment

Recruitment has begun in February 2011 and was completed at the end of April 2013. During that time 160 patients were enrolled.
